City of a Thousand Spies : The Virtuosic Spy: Book 3

The adrenaline rush of performance. In music, it made him a virtuoso. As a spy, it makes him deadly. Conor McBride has accepted bargains he may live to regret - assuming he lives through them at all. He's taken an undercover assignment in exchange for the chance to resume his career as a solo violinist. He's also agreed to a proposal from the woman he loves, but it isn't the type he had in mind. When their simple mission turns complicated, Conor and Kate discover everyone is hiding something - secrets as twisted as the fabled lanes of an old world city. Unraveling them will be anything but simple, or safe.
